Does this look like Nitrogen deficiency?

[montroller]

Got my first grow going on and one of my clones is starting to look a little different than the rest. I have a flood table going and the clones are in rapid rooters in hydroton. my nutrients are GH 3 part series and I initially mixed 2.5ml of micro, grow, and bloom per gallon.

The other clones in the table are starting to show signs of yellowing leaves but the one in the pictures is by far the most affected.

Clones have only been transplanted for 5 days if that helps.

Also I am using tap water that has been left out to dechlorinate and it tested at 0 ppm out of the facet.

Pick up GH's Micro/bloom and rock 6/9.... Fuck dealing with deficiencies

Yah I literally read about the lucas formula an hour after buying the 3 part series. I was thinking people mainly went that route to save some money so I just went with the 3 part schedule.

You think i should just say fuck the grow and do the 6/9? If so would you just do a res change today or should I wait until the first week is up?

Post up a whole plant shot. Usually N def. starts at the bottom lower leafs and works it way up.

It is kinda hard to get a good pic in there let me know if you need a better one.

Did you wash your hydroton? It could be a lockout from to low of ph or their hungry. Also how cold is it in there?

 

[montroller]

temps are floating at 70-74 during lights on and about 60-62 when they are off.

The hydroton was washed and soaked in PH'd water and the res PH stays at 5.8-6.0. I have had to add PH down a couple times. Do you think the PH in the actual hydroton is lower?

I topped off my res today with a gallon of water mixed with 10ml of micro. The res is 20 gallons total.

Also for a while that plant had the intake vent blowing right on it and when I noticed the leaf was curling I pointed the vent up a little more. Maybe the cold air (ambient of 62) was adversely affecting that one and that is why she is the first to show signs of deficiency?

check the underside of those leaves for bugs, eggs, etc.

Yeah to cold and the roots dont function right. I had mine on the concrete floor and they started to go limp and act like over watering issues. As for the clay yeah they like to go acidic but i dont think thats your problem.

The easiest solution is to see if their hungry so try that. Im not 100% but just by that photo id say their hungry.

I used an IR gun to check the temperature of the actual leaves and hydroton and they are both at 68-69. I did notice that when my tent is sealed and there is negative pressure the wind is pretty strong on those clones so I pointed the intake vents more upwards to prevent it blowing directly on them and it seemed to help. Temps rose 5 degrees pretty quick so I turned down the heater to maintain 74-76 in the room and the leaves are showing 73-74 on the IR gun.

I also checked for any bugs but didn't see anything on any of the plants.

Thanks for the suggestions everyone I will try to update on how it turns out.
